Bydentalicenses

Illinois is one of the most dynamic states in the country for dental assisting careers. From the broad professional landscape of the Chicago metropolitan area to the growing needs of suburban and rural communities throughout the state, Illinois offers a range of environments where skilled dental assistants are genuinely in demand. If you’re considering this career path, the state’s structured credential system and multiple entry points make it easier than you might expect to get started — and to keep advancing.

Why Choose Dental Assisting in Illinois?

The numbers make a compelling case. Illinois dental assistants earn a median salary of $41,780, with higher wages available in the Chicago metro area and competitive benefits packages increasingly common in larger group practices. The field is projected to grow 8% through 2031, reflecting sustained demand driven by an aging population and expanded access to dental care across the state.

But the appeal of dental assisting in Illinois goes beyond salary and job security. It’s a career built on daily human connection, clinical skill, and real contribution to patient health — with a credential pathway that rewards continued investment in your professional growth.

Illinois Dental Assistant Classifications

Illinois recognizes three distinct levels of dental assisting, each representing a different scope of practice and level of professional credentialing.

Basic Dental Assistant The entry-level position in Illinois requires no formal state registration. Basic dental assistants work under the direct supervision of a licensed dentist and are limited to foundational supportive duties. While this is a legitimate starting point, it carries a limited scope of practice — most assistants will want to move toward registration and expanded credentials.

Registered Dental Assistant (RDA) The RDA designation is required for dental assistants who wish to perform expanded functions in Illinois. Earning it requires completing state-approved training, passing required examinations, and obtaining specific procedure certifications. The RDA level comes with higher earning potential and a broader clinical role.

Certified Dental Assistant (CDA) Issued by the Dental Assisting National Board (DANB), the CDA is the most comprehensive credential available to dental assistants and carries significant weight with Illinois employers. It represents the fullest scope of practice and the strongest platform for long-term career advancement.

Basic Requirements

Before entering the field in Illinois, you’ll need to meet the following prerequisites:

  • Be at least 18 years of age
  • Hold a high school diploma or equivalent
  • Maintain current CPR certification
  • Complete OSHA bloodborne pathogens training
  • Complete HIV/AIDS training
  • Work under the supervision of a licensed dentist

Illinois is notable for its inclusion of OSHA and HIV/AIDS training as baseline requirements — a reflection of the state’s commitment to rigorous standards of patient safety and clinical practice.

Education and Training Pathways

Illinois offers two primary routes into dental assisting, with the right choice depending on your circumstances, learning preferences, and career goals.

Option 1: Formal Education Program

A CODA-accredited dental assisting program is the most comprehensive and efficient route to a successful career in Illinois. Programs typically run 9 to 12 months and combine classroom instruction, laboratory practice, and a clinical externship. Core curriculum areas include dental anatomy, radiography, infection control, dental materials, clinical procedures, emergency procedures, and the Illinois Dental Practice Act.

Programs are available through community colleges, technical schools, private career colleges, and university-affiliated programs across the state. Tuition typically ranges from $3,000 to $15,000, and financial aid options — including federal student loans, state grants, scholarships, workforce development programs, and employer tuition assistance — are widely accessible.

Option 2: On-the-Job Training

Illinois also allows entry into the field through direct employment under a licensed dentist. This pathway provides hands-on learning from day one, though it comes with a more limited initial scope of practice. Assistants who begin this way and wish to advance will need to complete formal coursework in radiography and other required areas to qualify for registration and expanded functions.

Certification Requirements

Several certifications are essential to working fully and effectively as a dental assistant in Illinois.

Radiology Certification is required for any dental assistant who will be taking X-rays. This involves completing an approved course and passing the corresponding examination.

CPR Certification must remain current throughout your career.

Coronal Polishing Certificate requires completion of an approved training program, a clinical experience component, passing an examination, and ongoing continuing education for maintenance.

Expanded Functions Certificate requires additional procedure-specific training, clinical experience documentation, and regular renewal. This certification is what unlocks the broader clinical responsibilities that define the RDA role.

Registering with the State

Once you’ve completed your education and obtained the necessary certifications, you’ll apply for registration through the Illinois Department of Financial and Professional Regulation. The process includes submitting documentation of your education and certifications, completing a background check, and paying the required fees.

Staying registered requires ongoing attention to your continuing education obligations and timely renewal of your certifications. The Illinois Department of Financial and Professional Regulation’s website is the authoritative source for current requirements and application materials.

Continuing Education Requirements

Illinois has clearly defined continuing education expectations for registered dental assistants: 36 hours every three years. Required topics include infection control, CPR renewal, the Illinois Dental Practice Act, emergency procedures, and OSHA updates. Staying on top of these requirements isn’t just a regulatory obligation — it’s a genuine opportunity to sharpen your clinical knowledge and stay current with evolving standards of care.

Additional certifications worth pursuing include nitrous oxide monitoring, sealant application, coronal polishing, local anesthesia monitoring, and digital radiography. Each expands your practical value on any dental team.

National Certification: The CDA Credential

While not mandated by Illinois, the Certified Dental Assistant (CDA) credential from the Dental Assisting National Board is one of the most impactful investments you can make in your career. Candidates must either graduate from a CODA-accredited program or have sufficient work experience, along with a current CPR certification.

Earning the CDA requires passing three examinations:

  • General Chairside (GC)
  • Radiation Health and Safety (RHS)
  • Infection Control (ICE)

The benefits are tangible: higher salary potential, increased job opportunities, professional recognition, interstate mobility, and eligibility for expanded functions. For Illinois dental assistants in a competitive job market — particularly in the Chicago area — the CDA can be a meaningful differentiator. Learn more at www.danb.org.

Where You’ll Work: Practice Settings in Illinois

Illinois offers a genuinely diverse range of professional environments for dental assistants.

In the Chicago metropolitan area, dental assistants have access to the state’s highest salaries, the greatest variety of practice settings, more specialty practice opportunities, and a robust professional network. The trade-off is a more competitive job market and a higher cost of living — but for those who thrive in a busy, high-volume environment, Chicago practices offer unmatched professional stimulation.

In suburban and rural communities, dental assistants often find a different and equally meaningful experience. Demand is growing as access to dental care expands beyond urban centers, and dental assistants in these settings frequently take on broader day-to-day roles with deeper patient relationships. Rural practice can also come with less competition for positions and, in some cases, eligibility for health professional loan forgiveness programs.

Practice settings across Illinois include private dental offices, group practices, specialty clinics, community health centers, educational institutions, university dental clinics, and public health facilities.
